LIQUID-STERILIZING- DEVICE.

Application filed June 16, 1913.

To all whom it may concern:

Be it known that I, VILLIAM B. FENN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Liquid-Sterilizing Devices, of which Ithe following is a specification.

The particular object of this invention is to provide means whereby a fluid can be quickly, thoroughly and economically sterilized'. In the sterilizing or cooking of canned goods a modicum of an aqueous solution of salt or sugar is oftentimes added. My invention is particularly adapted to sterilize such a solution and prepare it for introduction into the goods to be canned. My invention is also 'adapted for sterilizing soups or other liquids.

The invention is embodied in the construction herein shown and described and then particularly pointed out in the claims.

In the accompanying drawings illustrating one example of the invention- Figure 1 is a `central vertical section of the sterilizing device.

Fig. 2 is a plan view of the upper end of the device as shown in Fig. 1.

Fig. 3 is a horizontal section on the line .fr-m Fig. 1..

Fig. 4 is a view in elevation showing the device on va smaller scale in connection with a pump and other appurtenances.'

In the views 5 designates a casing forming a chamber 6. This casing consists of a tube like body having its ends formed to receive a wrench and internally threaded for the connection of other parts.

7 designates a tube closed at one end with a plug 8 secured by a pin 9. The tube 7 is threaded at 10 to be connected with the lower end of the casing 5 the part extending into the casing being provided with numerous small perforations 11. Within the tube 7 is another tube 12 also plugged at its upper end and provided with numerous small perforations 13. The perforated ends of the tube 7 and 12 are adjacent to each other within the chamber of the casing 5. The tubes 7 and 12 are connected by a T-connec tion 14 which is threaded at one end directly onto the lower end of the tube 7 and at the other end onto the exterior of the tube 12 by suitable reducing thimbles 15 and 16 said thimbles closing the opening between the Specification of Letters Patent.

connection and the tube 12. The lateral threaded opening 14a` of the T-connection receiveg a pipe 20 for the introduction of steam under pressure as hereinafter 'explained. The flow of steam through the pipe 20 is controlled by an ordinary valve, the handle of which is indicated at 21 (see Fig. 4).

The lower end of the tube 12 is connected with a suitable pump 17 the connecting member 18 containing an ordinary valve for controlling the flow from the pump into the tube 12. The said valve is operated by the usual handle as seen at 19.

The upper end of the casing 5 has connected to it a pipe or conductor with suitable elbows if convenient leading to the place where it is desired the discharge shall be made. Said pipe also contains an ordinary valve as seen at 22 for controlling or regulating the ow of liquid through it and a valve 23 for stopping the discharge when desired.

In practice the solution or material to be sterilized or cooked is forced into the tube 12 by means of the pump at a pressure of, say, forty pounds while the steam is admitted to the tube 7 from a suitable boiler at a pressure of, say, fifty pounds. The liquid in the tube 12 is sprayed into the space between the latter and the tube 7. Boing thus sprayed ythe steam admitted between the tubes commingles with and thoroughly and quickly 'heats the liquid and the two bodies thus pass out through the perforations of the tube 7 to the place of discharge. The pressure at which the liquid to be treated is forced through the pipe 7 and the pressure of the treating steam through the pipe 12 may be varied and regulated but it is advantageous, I have found, that the pressure of the treating steam be somewhat in excess of the pressure of the treated material because, as I believe, of the rapid condensation of the .steam in the operation.

l/Vhat I claim is:

1. Apparatus for sterilizing liquid comprising means for continuously flowing liquid under pressure through a passage, means for breaking up `such liquid en route, means for applying steam to such liquid while it is broken up, and means for regulating the discharge of the commingled liquid and ,steam in a manner to maintain intimate application of the steam to the brokenup liquid Without interrupting the continu,- ou's flow of the liquid.

2. Apparatus for sterilizing liquids comprising means for forcing the liquid under pressure through a reticulate plate into a chamber, means for delivering steam under pressure to such chamber, a Wall for Said chamber of reticulate material through which the commingled liquid and steam pass, and a regulable discharge outlet for the commingled liquid and steam yto Vary the intimacy of contact of the liquid particles and the steam.

3. Apparatus for sterilizing liquids comprising mean-s for fio-Wing such liquid under pressure through a perforated tube, means for introducing steam under pressure about said tube, perforated means for permitting passage of the connningled steam and liquid, and means for permitting the discharge of said commingled fluids, said means having a regulated opening to maintain the connningled fluid under regulated pressure and consequent temperature previous to Such discharge.
